I'm tryng to validate a field, so I've written this code:

        @api.one
        @api.constrains('code')
        def control_code(self):
            i=0
            a=1
            while i<9:
                if i==0:
                    if unicode.isdigit(self.code[0]):
                        a=i+1
                        raise Warning(("Warning!\nThe character %s must be a letter") % (a))
                elif i in range (1,4) or i in range (5,10):
                    if not unicode.isdigit(self.code[i]):
                        raise Warning(('Warning!\nThe character %s must be a number') % (a))
                elif i == 4:
                    if self.code[i] is not '/':
                        raise Warning(("Warning!\nThe character %s must be '/'") % (a))
                i=i+1
                a=a+1

Everything works fine, except for i==4. Even if I put a '/', I get the warning message.

Anyone knows why?

Hi friend:

Try this

if self.code[i] != '/':

raise Warning(("Warning!\nThe character %s must be '/'") % (a))

Use != (preferred) or <> (deprecated). See comparison operators : https://docs.python.org/release/2.5.2/lib/comparisons.html. For comparing object identities, you can use the keyword is and its negation is not.

Regards.
